Maybe it is just my ADHD but I can't concentrate with any sort of flashing light in the room.
My friend uses his RGB-lit gaming pc for his home theater and he can happily watch movies and TV with 8 RGB fan lights flashing.
It is beyond bizarre to me.
unhooked mine too. i have a large fan at the top of the case that blows upwards and it had this extremely illuminating blue light that was impossible to sleep with it on.
